EDITED: Now the note range goes from C3 to C7
Originally I heard the choir soundfont in this video and wanted it, but couldn't find it anywhere. This soundfont is something that I found (with no sign of author or any metadata) in a forum thread with a collection of orchestral sounds and edited it to create a similar sound of voices swelling in volume.
You'll find voice aahs and oohs, a mix of both slow and immediate attack versions of the sounds. See the demo included be...

This is the Concert Harp available at Sonatina Symphonic Orchestra. It has a default preset at bank 0 program 46 and also two presets at bank 1, program 45 for muted harp (without sustain) and program 46 is the same as the bank 0 preset.
Currently it's the free harp soundbank with the biggest number of good quality samples that I found online and it really sounds fine.

This is the second clarinet soundfont I did with a friend of mine. A 'Buffet Crampon R-13, 1953 edition' clarinet was used.I know that some sounds are no good, because my reed was sort of weird this day, and I didn't warm up. Watch for a new version soon! And give me your feedback so I can do better next time I record myself!

This Sf2 Has been sampled and editedrom scratch. It named BETA because it has not been tested by anyone else but me. The samples are all 'real' from a K. KAWAI grand. I would like any feedback because I will be sampling another using 2 mic's and a stereo mixer etc.

Not really easy to use, but the harpes and reeds might be good for droning stuff.
Volumes are a little off and not all notes are mapped, but you might find something insteresting here.

Interesting vocal aaahs (or eees actually). Not really on par with professional vocal samples, but you might like if you're looking for something different.

I recorded this today using myself and a mic. You won't find these samples anywhere else.
